I See What You Mean

Here's another look at public health stats from various countries around the world. As with the first installment of this series , the countries included here rank in the Top 5 in at least one of four categories: Life Expectancy (longest), Under-5 Mortality (least), Health Care Expenditure per Capita (highest), and Prevalence of Physicians (greatest). (Source: Nationmaster.com .) NOTE: Unlike the previous chart, this one omits Macau and Hong Kong, which had made the cut because of their populations' longevity. I omitted these two Chinese territories because the only available figures on the geographical distribution of physicians reflect China as a whole. Result: not only does this camouflage the serious disparity between urban centers and rural districts, it obscures any geographical specifics. Comments and questions are invited.

In selecting my international sample, I decided to examine the top 5 countries in each of four categories:  Longest life expectancy (longest) Lowest infant mortality (least) Highest health care expenditure per capita Greatest prevalence of physicians My source for these stats was the invaluable Nationmaster.com . (Note:  As a proxy for Hong Kong and Macau, I've used China's expenditure figure, since they've both been under Chinese rule for the last decade.) Given where the two dimensions of this graph ultimately lead, I've nicknamed it "Death and Taxes (Sorta)."

Jess Bachman of Wallstats.com , creator of the well-known Death and Taxes poster, has turned his eye to the U.S. government's unemployment statistics. Back in January he published a flowchart clarifying how the government determines who is officially Unemployed and who is merely overlooked. ( Here's how that determination is described verbally by the Bureau of Labor Statistics.) What's more, the official numbers have gone up since January. As of the end of June, the official figure is 9.5 percent. Has the Obama administration come up with a new tally to include all the undercounted (I hope)? Or are things just going to hell in a handbasket (I fear)? Click here to see the whole thing. Nice work, Jess.

Created by a couple of UK computer science students, this newly upgraded aggregator/search engine delivers results that are both broad and deep. Tags are used extensively and to good effect, but the infoviz applications are where the action is. The Network widget is probably my favorite. To use, hover over a small graphic image to highlight its connections with other items in the network. Hover over bits of text for pop-ups providing additional information. Double-click a node if you want to drill down. If you're looking for news from a certain region, click the Hot Spots map widget and drill down from there. You can further refine the search by filtering the topic of the news stories. Unfortunately, the Trends app is buggy, poorly explained and therefore far less useful. And Silobreaker's collection of pre-set topics (global issues, tech, science, business, energy and world) is certainly incomplete. Even so, the site's dashboard-style interface provides lots of entry p...

As thousands and perhaps millions take to the streets in Tehran to protest Iran's (alleged) election fraud, the UK's Guardian goes nitty-gritty, posting a data set of polling results. * The paper ends its report thus: "Can you do something with this data? Please post us your visualisations and mash-ups below or mail us at datastore@guardian.co.uk ." Its story also links to data maps from Fivethirtyeight.com and Iran Tracker. (Elsewhere at Fivethirtyeight, Nate Silver considers the statistical analysis that ostensibly proves the election was rigged -- in other words, the basis of the protestors' unrest.) Here's the direct link to the election data, in case anyone out there feels like having a go at it; I hope I'll have some time to muck around with it myself. DATA: Full Iranian election results by province including turnouts and 2005 results. Download them as a spreadsheet. *Per the story: "The figures we've uploaded are, as far as we can work...

Along with Fast Company (and me ), Business Week asserts that good information graphics and info design have business value. An admiring profile of Edward Tufte — with accompanying slide show , natch — is featured in BW's recent "Voices of Innovation" package: Next to a bad example of a graph, he positions a sublimely clear treatment, often using the same data. Simple as it sounds, the effect has proved to be riveting for a generation of nonprofessional designers. Tufte's work is relevant to anyone who needs to write or present information clearly, from business executives to students.   In dismantling some of the worst habits of two-dimensional design, he has framed new analytical terms that flicker through many design conservations [sic]*. * Conventions? Conversations? Or something else? And, more important, have any readers out there recently had a "design conversation" at work? (Media folks, you're DQ'd, sorry.) Do tell.

Portuguese infoviz enthusiast Jorge Camoes has spent the last year and a half writing informed, insightful blog posts on the field, complete with examples and citations. To his credit, he approaches everything -- even the revered work of Edward Tufte and Stephen Few -- with loving skepticism. I'm gratified, too, that he seems to agree with me on one central point: Snazzy tools alone don't get you good data visualization. It all comes down to putting serious thought into the project before you plot the first data point. In future posts we'll discuss more of Jorge's ideas. Bem feito, o Sr. Camoes!
